The National Security Agency (NSA) are reported to have monitored the calls of 35 world leaders, and over the course of one month last year, they monitored more than 60 million phone calls made in Spain, alone, according to a Spanish Newspaper, El Mundo.

Edward Snowden, former NSA contractor, leaked documents that indicated that phone calls that were made in Spain during December 10, 2012 and January 8, 2013 were subject to US observation. The NSA were reported to have monitored numbers and the durations of phone calls, but not their content. Also, NSA technology enabled them to monitor emails and text messages, but it has not been confirmed if those methods were used as well.

 The discovery makes Spain the third Western European country in less than a week to report that NSA surveyed their phone calls. France and Germany were the other two countries that were monitored, and the heads of their nations are demanding an explanation. NSA surveillance in Germany dates back to 2002, according to some reports.

Interior Minister Hans-Peter Friedrich was quoted saying, "If Americans intercepted cellphones in Germany, they broke German law on German soil... those responsible must be held accountable."

Now, under fire for these claims, debates are rising, questioning whether President Barack Obama had knowledge of the wiretapping. According to Fox News, a "high ranking" NSA official indicated that Obama not only knew of NSA surveillance but ordered that it continue.

Though the organization, itself, has denied any claims that the NSA director Keith Alexander ever spoke with Obama about any intelligence operations. One official stated that the president didn't sign off on those types of procedure.

Reportedly, the president has directed that the National Security Council review their surveillance capabilities. "The United States is reviewing the way that we gather intelligence to ensure that we properly account for the security concerns of our citizens and allies and the privacy concerns that all people share," Caitlin Hayden, NSC, spokesperson said.

European leaders are calling for a new deal with US intelligence organizations, one that would allow for the tracking on terrorism, and the prevalence of essential alliances.
